you shall set up for yourself: in the Jordan, and after this, you shall take out other [stones] from there, and out of this [second set of stones], build an altar on Mount Ebal. Consequently, we find that there were three places [at which constructions] of stones [were set up]: a) Twelve [stones were put together] in the Jordan, b) the same [number of stones set up] at Gilgal [i.e., the Israelites’ first stop in the land of Israel,] and c) the same [number of stones set up] at Mount Ebal. The above is taught in Tractate Sotah (35b) [where the Talmud, citing Chapter 4 of Joshua, proves the above].

3When you cross, you shall write upon them all the words of this Torah, in order that you may come to the land which the Lord, your God, is giving you, a land flowing with milk and honey, as the Lord, God of your forefathers, has spoken to you.
